The Volvo S90 has two tire size models: 245/45R18 and 255/40R19. The first number, 245, indicates the tire width is 245MM. The 45 represents the aspect ratio of the tire's cross-section at 45%, meaning the height is 45% of the width. The letter R stands for radial tire, and 18 indicates the rim diameter is 18 inches. The Volvo S90 has a top speed of 180km/h, accelerates from 0-100km/h in 7.2 seconds, and has a fuel consumption of 6.7L per 100km. In addition to the model, the tire also displays the following common data: Tire cord material: Indicated by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, ZG for steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters from A to Z represent speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, such as standard rim 5.00F.

I've been driving a Volvo S90 T5 for a while, and the tire size is usually 235/50 R18, but higher-end models like the Recharge can use 245/45 R19. This size matches the vehicle's weight and handling system, making it feel stable, especially at high speeds or on wet roads; the strong grip reduces the risk of skidding. Tire choice is crucial, with the factory often using Michelin or Pirelli, which are reliable and can also reduce noise. I check the tire pressure every time I service the car, keeping it around 2.5 bar; when the wear is deep, I replace them—don't skimp on this. Remember to check the model on the tire sidewall label or manual to avoid modifications that exceed limits and affect suspension safety. Driving safety comes first, and regular maintenance can keep the car running for a long time.

After frequent car repairs, I've learned that the standard tire for the Volvo S90 is 235/50 R18, while the top trim sometimes comes with 245/45 R19. Model details matter: 235 indicates width in millimeters, 50% aspect ratio, and 18-inch wheels; matching the V-speed rating ensures proper ABS function. During installation, ensure proper alignment to reduce uneven wear; check tread depth monthly and consider replacement if below 4mm. Maintenance tips: clean wheel hub dirt during car washes, adjust tire pressure seasonally; significant summer-winter temperature differences can cause pressure loss. From a safety perspective, tire issues may trigger ESP failure, creating hazards at high speeds. Choose OEM-spec brands like Bridgestone for durability and safety. The manual contains specific diagrams—don't trust misleading advice from small shops.

Hey buddy, the Volvo S90 offers an amazing driving experience! The standard tire size is 235/50 R18, providing strong grip and stable cornering; I've upgraded to Pirelli P Zero tires, which make highway driving incredibly enjoyable. Tire size affects handling; larger wheels enhance sportiness but may increase bumpiness. Maintenance is straightforward: check tire pressure monthly with a gauge, and clean the rims during car washes. Driving pleasure relies on quality tires; the S90's design emphasizes safety, with tires perfectly matched to its all-wheel-drive system. Don't overlook the small details; when replacing tires, choose brands and specifications that match the original to enhance performance. A long-distance drive will show you how crucial tires are; ensure they're comfortable and durable.
